FISHING TOOL.

Application filed November' 20, 1924. Serial No. 751,080.

T all 'whom t 'may concern.' Y

Be it known that we, RICHARD A. Mason and VALTER STONE, citizens of the United States, residing at Long Beach, in the county of Los Angeles and State of Cah- 1 fornia, have invented new and useful Improvementsl in Fishing Tools, of which the following is a. specification.

This invention relates to improvements in fishing tools.

It is an objectof this invention to provide a fishing tool adapted to engage upon and remove small articles, such as cones, discs and the like, from the bottom of deep wells.

It is a further object of this invention to provide a fishing tool consisting of a body carrying a plurality of fish engaging mem` bers, which shing tool may be lowered in to the well with the fish engaging members inV contracted position; and to provide means whereby ywhen the bottom of the well is engaged by the fishing tool, the fish engaging members will be forced into eX-y panded position and then allowed to contract upon any7 fish which they may encounter.

YVith the foregoing and other objects in view which will be made manifest vin the following detailed description and pointed out in the appended claims, reference is had to the accompanying,drawings for an illustrative embodiment of the invention, wherein: v

Figure 1 is a vertical section through a well showing the fishing tool in position after having encountered' the bottom of the well;

Fig. 2 is a view similar to Fig. 1 showing the fish engaging members forced into Vexpanded position;

Fig. 8 is a similar viewto Figs. 1 and 2 showing the fish engaging members after having been allowed to 'contract upon a fish; Fig. 4 is a view taken substantially on the line /1-4 of Fig. 1; I

Fig. 5 is a view taken substantially on the l line 5%-5 of Fig. 2; and

Fig. 6 is a section taken substantially on the line 6 6 of Fig. 3Q Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved fishing tool consists of a cylindrical body 10, in which isU formed arsuitable spider Y11. The interior of the body 10 is preferably threaded, as at 12, to permit the body to drill tube 13.

suitable enlargement which in the present form of invent-ion consists of a nut 15 adapted to engage the spider 11 and limit the downward movement ofl the stem 14 with respect to the body. Adjacent the lower edge of the cylindrical body 10 there are formed a plurality of lugs 16 and the upper ends of the fish engaging members 17 are bent about pinsy 18 extending toward each other from the lugs 16. The pins 18 serve to pivotally connect the fish engaging members to the cylindrical body 10. Upon the inner.` surfaces of the fish engaging members 17 there are provided shoes 19 which may be secured in position by means of screws 20 and cap screws 21. The cap screws 21 serveto additionally` secure leaf springs 22 to the fish engaging members 17. The leaf springs 22 have their upper ends in engagement upon the exterior'surface of the body 10 and lserve to A suitable stem 14 extendsV urge the fish engaging members 17 into i contracted and-3. f

The stem lll carries a head 23, the upper end of which is conical in form, as. indi position, as .shown in Figs. 1

cated at 24, and the lower end of which is cylindrical in form, as indicatedat k25. This head 23 engages the shoes 19 carried upon the inner sides of thefish engaging members 17 and upon upward movement of the stem 11i relatively to the body 10 causes the yfish engaging members 17 to be expanded against the action of theleaf springs 22.

VRibs 26 are formed upon the cylindrical engaging member. The fingers 27 serve to cause all of the fish engagingl members 17 to expand and contract simultaneously, and the arms 28 extend across the opening between the lowerk ends of the fish engaging members 17 when these fish engaging ineinbers are in expanded position, so as to prevent the fish F from slipping between the lower ends of the fish engaging members 1T lows: The body is secured upon the lower Y end of the drill tube 13 and the whole is lowered into a well in the position shown in Fig. 1. In this position the heat 23 is disposed below the shoes 1.9 carried by the fish engaging members 17 and the nut 15 restsupon the spider 11. rlie leaf springs 22 urge the fish engaging members 17 into contracted position about the stem 11i above the head s3. When the portion 11i of the stem 1a'- engages the bottom of the well, downward movement of the body 10 causes the 'head 23 to engage the shoes 19. lhe conical portion 24 of the head 23 produces the expansion ofthe fish engaging members 17. As, the shoes 19 engage the. cylindricalk portion 25, the body 1() maybe lowered without causing further expansion or contraction `of the fish engaging members 17. Upon still furtlierlowering the body 10, the shoes 19 will slip over the bottom edge of the cylindrical portion 25 of theA head 23 and the springs Q2 will cause the fish engaging members 1'? to` contract so as to engage or clamp upon a vfish F, which 'fish may be clamped between the separate fish engaging members or between one-or more fish engaging members 17 and the portion 111 of the stein 14.

1t will be readily appreciated that the iniprovediishing tool. cannot be readily employed inreinoving broken sections of drill tube andV such articles from the bottom of a well, but is highly advantageous for picking up and removingsinall articles as above stated. f

Vhen it is desired to reset .the fishing tool, the fish engaging members 17 may be pulled apart against vthe action of the springs 22 to permit the head 23 and the `stein-'14 tof slide downwardly within the body 10, the head 28 passing between the shoes 19. 1f desired, the cap screws 21 may be loosened so as to reduce the actio-n of the leaf springs 22 and this will permit the fishfenga-ging members 17v to Yswing* outwardly` veryeasily, thereby permitting the head 23 to slip downwardly between the shoes 19. It will be understood that various changes inthe detail. of construction may be made without departing` from the spirit or scope of the invention as defined by the appended claims.

We claim: Y 4
